Probe into WA prospector's death continues

There is no indication that West Australian prospector Raymond Kehlet was murdered but investigations into his death are continuing, police say.

Mr Kehlet was found dead at the bottom of a 12-metre deep mine shaft in the Goldfield's region after an extensive land search for him and his wife, who were last seen on March 22.

Police have refused to say how Mr Kehlet died but are seeking information about items the couple were carrying and the movements of people in the area when they disappeared.
